Dip-Switches
(DS1, DS2)
Adjustment outputs
With these outputs and a potentiometer, the user can obtain a variable an-
alog voltage for adjusting the servo system during setup.
The voltage, with no load, at these pins is ±15 V DC.
The electrical circuit necessary to obtain a reference voltage and the rec-
ommended resistance values to obtain an approximate range of ±10 V
DC for the Vref are described next:
